Abstract: The invention relates to a wide-mesh fabric (1) treated with bonding agents, in which warp thread bundles (4) comprising a plurality of warp threads (3) and weft thread bundles (6) comprising a plurality of weft threads (5) surround the inner meshes (7), wherein the warp threads (3) are interwoven with the weft threads (5) at the intersections (8) of the warp thread bundles (4) and weft thread bundles (6) which extend at a right angle to each other. To firmly fix the warp and weft threads the warp thread bundles (4) are divided into a first warp thread group (4') and a second warp thread group (4") and the first warp thread group (4') crosses over the second warp thread group (4") of the same warp thread bundle (4) for each mesh (7) in the manner of a half-doup thread, and at the intersections (8) the warp threads (3) of both warp thread groups (4' 4") are interwoven extending in substantially mutually parallel relationship with the weft threads (5). Mesh fabrics of this kind can be used for reinforcing ground surfaces, road surfaces, layers of mortar and the like and for poultry farming and as fishing nets.

Inventor: SULTAN ISRAEL DANIEL
IPC: H04L29/12
Filed: 2001-02-27
Abstract: A network address translation gateway (20) provides normal network translation for IP datagrams traveling from a local area network (10) using local IP addresses to an external network (30), but suspends source service address (port) translation when the port is reserved for a specific protocol, such as the ISAKMP "handshaking" protocol that is part of the IPSec protocol model (FIGs. 2 and 3). ISAKMP exchanges require both source and target computers to use the same service address (port). By providing a network interface that does not translate the source service address (port), this gateway enables the initiation and maintenance of secure, encrypted transmissions using IPSec protocol between a local area network using local IP addresses and servers on the internet.

Inventor: BOWMAN DON
IPC: H04L29/08
Filed: 2003-03-11
Abstract: The invention relates to a system and method for reducing and reconstructing state entries for initiator messages in a communication network. It compares a set of common options to each initiator message. If the message has the common options, no state entry is created for the message. This saves resources in systems such as Peer to Peer networks utilizing TCP/IP, where there is often no acceptor (SYN/ACK) to an initiator (SYN). By utilizing the present invention an agent dealing with communications need not maintain state for every connection. Upon receiving an acceptor message corresponding to an initiator message, the agent may create a state entry from the common options.

Title: Agents for the treatment of viral infections
Inventor: TESSMER UWE
IPC: A61P25/28
Filed: 2001-10-11
Abstract: The invention relates to agents for the treatment of viral infections, in particular, infections with hepatitis and retro-viruses. Said agents inhibit the release, maturation and replication of both retro-viruses and also hepatitis viruses. In the example of human immune deficiency virus (HIV) and hepatitis-B viruses it has been shown that proteasome inhibitors block the release of virus particles and the infectiousness of the released viral particles and thus the reproduction of the viruses. The proteasome ihibitors affect the activities in the ubiquitin/proteasome pathway, in particular the enzymatic activities of the 26S and the 20S proteasome complexes. The application for the above invention lies in anti-retroviral therapy, particularly the treatment of HIV infections and AIDS and in the anti-viral therapy of hepatitis infections, in particular the treatment of acute and chronic HBV and HCV infections and the associated liver carcinomas.

Title: Multi-axle running gear for automotive trucks, tractors, trailers, and semi-trailers
Inventor: CURRY N ROYCE
IPC: B60G9/00
Filed: 2003-05-12
Abstract: The invention provides new multi-axle running gear for automotive transport tractors, trailers and semi-trailers, the minimum requirement being that the running gear has at least two longitudinally spaced axles mounted parallel to one another, one relatively closely behind the other. One of the axles is mounted for substantial limited transverse movement along its longitudinal axis so that it will move sideways under transverse scrubbing forces applied thereto by the engagement of its running wheels with the ground as the vehicle negotiates a curve or corner. This gives via a relatively simple and economical structure, consisting principally of an axle member mounted for sliding movement in a supporting housing, that provides steering movement to its wheels equivalent to that of a self-steering axle, such steering movement reducing the transverse scrubbing and improving the yaw stability of the vehicle. The preferred minimum movement of the axle from a neutral position is equivalent to a steering angle of at least 10 degrees, while a practical amount for most applications will be equivalent to a steering angle of 20 degrees. Numerous combinations are possible in the standard two-wheel, three-wheel, or four-wheel bogie and tractor configurations, comprising such slip-steer axles in combination with fixed, self-steering and lifting axles.
